Check the coolant temperature sensor, and the coolant level sensor and make sure that they are plugged in. Remove the harness to them and check the sensor for resistance. For the level sensor, if the coolant is full, Hiall. I have a 2006 Q7 3.0 TDI SE, 60k miles. I had the original battery changed around 18 months ago to try and resolve slow starting (5+ seconds of cranking and eventually white smoke, both in summer and winter). This cranking caused the EPS/ ABS warnings on the dash, as the long cranking caused the battery voltage to drop. Genericsensor resistance vs temperature is in the chart below. From the chart I think you will see the problem you are facing. At 80 C, for example, a sensor will be between 275 ohms and 375 ohms or 325 ohms +/- 15%. Looking at it the other way round, a sensor at 325 ohms could be interpreted by the car to be anywhere between 75 C to 85 C. Howmuch does a Engine Coolant Temperature (ECT) Sensor Replacement cost? On average, the cost for a Audi Q7 Engine Coolant Temperature (ECT) Sensor OriginallyPosted by B6JoeS4. This is a DIY to replace the coolant temperature sensor on a 3.0 engine. You will often get a check engine light when this part fails and you will get the code 16500: Engine Coolant Temperature Sensor (G62): Implausible Signal. Or you may get 16502: Engine Coolant Temperature Sensor (G62): ACwas blowing ice cold as normal, stopped at home to drop some things inside and left the car running in the driveway. Two minutes later we get back in and the AC is “on” but not cooling/blowing ambient Charlotte NC lava-temp summer air. Verified the compressor was NOT engaging and went to work on the googles.
